Can Toilet Paper be Backwards?

We just received a shocking dressing down from our partner. We've just been told that we have not been putting the toilet paper in the holder the "right way." We've been told that we "put it in backwards." What? Never heard this before....

Apparently, we've just learned, TP should fall out of the holder, "waterfalling" down the front and NOT lick up from the back (the "underhand" method, apparently for criminals).

We'd like to see if this is a generally held belief, and we've been in the dark all along. What do you think?
